10 Laps at the Aquatic Center

I purchased an Aqua-Vee system, designed to attach to one's pool tiles and convert it into an Olympic size pool. The concept is great, however, the suction cups don't want to stick to my tile. There is an alternative - adding adhesive squares to create a different texture. I don't want to damage my pool, and much to my disappointment, I'm sending it back.
I woke up with a migraine and almost didn't go swim. But I did go to the Aquatic Center, did a 2 lap warm-up, 6 laps and then a 2 lap cool down. The cold water really helped my head.
